## Algebra: A Combined Approach (4th Edition)

The ordered pairs $(0,3)$ and $(2,-1)$ are not solutions.
We replace $x$ with $0$ and $y$ with $3$ and see if a true statement results. $x-y \gt 3$ $(0)-(3) \gt 3$ $0-3 \gt 3$ $-3 \gt 3$ False The ordered pair $(0,3)$ is not a solution since $-3 \gt 3$ is a false statement. We replace $x$ with $2$ and $y$ with $-1$ and see if a true statement results. $x-y \gt 3$ $(2)-(-1) \gt 3$ $2+1 \gt 3$ $3 \gt 3$ False The ordered pair $(2,-1)$ is not a solution since $3 \gt 3$ is a false statement.
